I have a small closet (4x6) that I use to house my AV equipment (receiver/consoles/etc). This works great, but as the closet is in an upstairs room it gets quite warm in the summer. I would like to add a ventilation fan to that closet to exhaust some of the heat, but would prefer to avoid adding another exterior vent on the house.
I know venting bathroom/kitchen exhaust into attic is a bad plan due to moisture issues, but I am wondering if it would be OK in this case. The only air venting from the room would be warm dry air.
Any thoughts on just sticking a basic bathroom fan up their and venting into open space above the insulation (attic does have its own vents)?
